ORGANIZATION ; Montana Department of Fish, Wildlife and Parks 

 ( MDFWP ) 



TITLE OF STUDY ; Western Montana Fishery Investigation: Inven- 

 tories and Surveys of the Upper Clark Fork River (Druramond to 

 Milltown, Rock Creek and the Blackfoot River) 



CONTACT ( S ) ; Dennis Workman - Montana Department of Fish, Wild- 

 life and Parks, Missoula - 721-5808

OBJECTIVE ; Evaluate the condition, distribution and abundance 

 of game fish in waters of the study area. 



DURATION : 1967 - Indefinite 



CURRENT STATUS : Trout population estimates have been conducted 

 at the following locations: 



Clark Fork River 



Bearmouth (below Druramond) 

 Bonita (above Rock Creek) 

 Turah (above Milltown) 

 Milltown (below the dam) 



Blackfoot River 



Johnsrud Park (near mouth) 

 Lincoln

 1972 



Water temperatures have been periodically monitored (with 

 recording thermographs) within the study section since 1976. 



Three fish population study sections on Rock Creek have 

 been periodically sampled since the early 1970 's. Creel census 

 data is available for Rock Creek since the mid-1950 's. Fish 

 movement (jaw tagging) and growth rate studies have also been 

 conducted. 



FUTURE ACTIVITIES : The Bearmouth, Turah, Milltown and Johnsrud 

 Park study sections will be monitored yearly. The Rock Creek 

 sections will be periodically monitored. The monitoring stations 

 at Lincoln and a new station on the Blackfoot River near Ovando 

 may be added. The Bonita Station will probably be dropped.
